Kinda ambiguous but I think "artifacts" should cover all instances of artifacts, including xeno relics and sorted artifacts. I'm interested to hear the answer myself, since this will be pertinent to my srp request

Yes, it should include all 3 forms of Artifact commodities currently ingame. Such lines were never updated to reflect the addition of Sorted Artifacts and Xeno Relics.
Should be confirmed, at best in fancy green.
